Acebutolol HCl is a selective, hydrophilic beta-adrenoreceptor blocking agent with mild intrinsic sympathomimetic activity for use in treating patients with hypertension and ventricular arrhythmias. It is marketed in capsule form for oral administration. Acebutolol HCl capsules are provided in two dosage strengths which contain 200 or 400 mg of acebutolol as the hydrochloride salt.
HYPERTENSION: Acebutolol hydrochloride capsules are indicated for the management of hypertension in adults. It may be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics.
VENTRICULAR ARRHYTHMIAS: Acebutolol hydrochloride capsules are indicated in the management of ventricular premature beats; it reduces the total number of premature beats, as well as the number of paired and multiform ventricular ectopic beats, and R-on-T beats.
Published Studies Related to Acebutolol
Effects of grapefruit juice on the pharmacokinetics of acebutolol. [2005.12]
AIMS: We aimed to investigate effects of grapefruit juice on acebutolol pharmacokinetics... CONCLUSION: Grapefruit juice caused a small decrease in the plasma concentrations of acebutolol and diacetolol by interfering with gastrointestinal absorption. The interaction between the grapefruit juice and acebutolol is unlikely to be of clinical significance in most of the patients.
Comparison of the effect of perindopril and acebutolol on cerebral hemodynamics in hypertensive patients. [2001.01]
PURPOSE: The aim of the study was to compare effect of perindopril (4 mg once a day) versus acebutolol (400 mg once a day) on cerebral hemodynamics in hypertensive patients... CONCLUSIONS: Among patients with mild-to-moderate hypertension both acebutolol and perindopril beneficially decreased cerebrovascular resistance and increased the CBF index in comparison with placebo. The increase of CBF index was greater after perindopril than acebutolol, which suggests a more significant improvement in cerebral perfusion by perindopril. The non-invasive transcranial Doppler ultrasonography method of CBF velocity measurement may contribute to choosing optimal antihypertensive therapies and to monitor their effect.
[The comparison of clinical effectiveness of perindopril and acebutolol in the primary hypertension treatment] 
Hypertension is one of the most important risk factors for ischaemic heart disease and stroke. The aim of our study was to assess the antihypertensive effect of angiotensine converting enzyme inhibitor (perindopril) versus beta blocker (acebutolol) in hypertensive patients... After 3 weeks of the treatment we observed BP systolic and diastolic normalization, but more patients had systolic BP normalization after perindopril treatment.
Comparison of acebutolol with and without hydrochlorothiazide versus carvedilol with and without hydrochlorothiazide in black patients with mild to moderate systemic hypertension. [1999.07.01]
In the present study, we assessed the antihypertensive efficacy of acebutolol 200 mg versus carvedilol 25 mg once daily, given as monotherapy for 3 months to 40 black patients (20 patients in each group, mean age 53+/-10 years, 24 women) with mean blood pressure (BP) during the day >90 and <110 mm Hg.
Effectiveness of digitalis with or without acebutolol in preventing atrial arrhythmias after coronary artery surgery. [1997.04.15]
In this study, a beta-adrenergic blocker in combination with digoxin provided marginal protection against atrial fibrillation/flutter after coronary artery surgery. The economic comparison of patients who did and did not develop atrial fibrillation/flutter indicates that prevention of these arrhythmias can have a significant impact on length of hospital stay and cost of this common surgical procedure..

An Open-label, Single-dose, Two-treatment, Randomized, Cross-over Study to Investigate the Effects of the SLCO2B1 c.1457C>T Polymorphism and Apple Juice on the Pharmacokinetics and Pharmacodynamics of Acebutolol in Healthy Korean and Japanese Volunteers [Completed]
An open-label, single-dose, two-treatment, randomized, cross-over study to investigate the
effects of the SLCO2B1 c. 1457C>T polymorphism and apple juice on the pharmacokinetics and
pharmacodynamics of acebutolol in healthy Korean and Japanese volunteers
Ablation vs Drug Therapy for Atrial Fibrillation - Pilot Trial [Completed]
The CABANA pilot study is designed to test the hypothesis that the treatment strategy of
percutaneous left atrial catheter ablation for the purpose of the elimination of atrial
fibrillation (AF) is superior to current state-of-the-art therapy with either rate control
or anti-arrhythmic drugs for reducing AF recurrences at 1 year follow-up.
Treatment of Mild Hypertension Study (TOMHS) [Completed]
To compare the effects of nonpharmacologic therapy alone with those of one of five active
drug regimens combined with non-pharmacologic therapy, for long- term management of patients
with mild hypertension.
Prediction of Response to Neoadjuvant Therapy in Rectal Cancer [Not yet recruiting]
The purpose of this study is to determine whether 18F-FDG-PET-CT and texture analysis of MRI
performed 9 weeks after Neoadjuvant Chemo-radiotherapy in patients with locally advanced
rectal cancer has the ability to identify patients with Complete Response.
Kangaroo Mother Care to Prevent Hypothermia in Term Infants [Recruiting]
The overall hypothesis is that better adherence to Kangaroo Mother Care (KMC) in combination
with existing WHO thermoregulation care will reduce the incidence of moderate hypothermia
(32-36 degrees C) or severe hypothermia (<32. 0 degrees C) in term infants (greater than or
equal to 37 weeks of gestational age) when compared with routine WHO thermoregulation alone.
